BRICK-Kim.

To will ull/120m it may concern:

Be it known that I, JOHN MANYFENNY, of New Brighton, Beaver county, Pennsylvania, have invented a new and useful Im rovement in Brick-Kilns, of which thefol owing is a full, clear, and exact description, refer-v ence being had to the accompanying drawings, forming part of this specification, in which v Figure 1 is a horizontal'section of a kiln embodyin my invention, the section being taken on ghe line I I of Fig. 2, one half the section being below the kiln-Hoor and the other half above said floor.

l Fig. 2 is an interrupted sectionA on the line II II of Fig. 1. Fi 3 is a fragmentary section on the line III II of Fig. 1, showing one of thecharging doors. Fig. 4 is a detailperspective view of one of the removable flue-cover bricks, and Fig. 5 is a section on the line V V of Fig. 1.

My invention relates to the class of downdraft-kilns used for burning brick, crockery, and other clay and pottery products wherein the furnaces and stacks are circumferentially arranged, and the ioor is provided with ports or o enings communicating with flues below the oor and leading to the stack.

, My object is to provide a downdraft-kiln in which the heat is effectively distributed over the entire iioor, in which a maximum floorspace 1s provlded, and 1n which provlslon 1s l made for ready and yconvenient access to the a strong draft at this point.

flues for any purpose.

I obtain the foregoing objects by the novel construction, arrangement, and combination of the parts, all. substantially as hereinafter described, and pointed out in the appended claim. r

In the drawings, 2 designates the iioor of the kiln, below or in which are formed a plurality of concentricallyarranged circular lflues 3, each of which is connected by radial flues 4 with a stack 5. The flues 3 may be continuous throughout their length; but I prefer to break them up into sections in the manner shown in Fig. 1 and to provide leach section with a flue 4, leading to a stack. I also provide the short `enlarged flues 6, which lead lfrom the inner circular flues 3 to the central portion of the kiln, in order to provide for Each of the circular flues 3 and also, prefuerably, the'` iiues 6 are covered by means of a plurality of separate removable bricks 7 one of which is shown in detail in Fig. 4' and each of which is provided at one side with a recess Specification of Letters Patient. l

' are indicated at 9. These furnaces have the grates 10 and the o enings 11 leading through their inner walls to the interior of the kiln. Each furnace has separate lateral walls, whereby the spaces lbetween them may be utilized.

v12 indicates the charging-doors for the kiln, of which any desirednumber may bey provided.

- The heat and products of combustion from the furnaces9 pass tothe interior of the kiln through the ass'ages 11 and are thoroughly distributed t oughout the kiln by means of.

the flue-and-draft `arrangement described.

The flue-covering bricks 7 are set so that their upper surfaces are level with the surface of the floor 2, and the arches 13 over the radial flues 4 are filled over, as'indicated at 14 in Fig. 5, to also provide a flush surface,so thlat a flat level oor is provided for the entire ki n.

It is obvious that the number of circular and radial flues may be more or less than shown in the drawings, as may be desiredgfacf. cording to the size of the kiln, and that the 'Y number'of stacks and radial flues maybe changed accordingly without affecting my inf vention.

What I claim is *y In a downdraft brick-kiln, a series of con-f.l

centric circular flues in the floor of the kiln,

the inner one of said flues having short en-r l larged iiues extending inwardly therefrom to the center of the kiln, and providing for an effective central draft, and removable covers for the said ues substantially as described'.

In testimony whereof I have hereunto set my hand. p
